Answer: B. 144
Step-by-step explanation: It's 144 because if you multiply 14 x 24 you get 336 and then you multiply 8 x 24 and you get 192. Now you subtract 336 - 192 and you get 144.

-3x(7x-4)+6x-(13-24x²)
Answer:
[tex]3x^2+18x-13.[/tex]Step-by-step explanation:
Step 1:
Equation should be:
[tex]((0-(3x*(7x-4)))+6)-(13-(2^3*3x^2))[/tex]Step 2:
Equation should be:
[tex]((0-3x*(7x-4))+6x)-(13-24x^2)[/tex]Step 3:
Factoring [tex]3x^2+18x-13[/tex]The first term is [tex]3x^2[/tex]. It's coefficient is 3.The middle term is +18x, it's coefficient is 18.The last term, "the constant", is -13.Step 1:
Multiply the coefficient of the first term by the constant 3 * -13 = -39Step 2:
Find two factors of -39 whose sum equals the coefficient of the middle term, which is 18 . -39 + 1 = -38 -13 + 3 = -10 -3 + 13 = 10 -1 + 39 = 38 Observation : No two such factors can be found !!Conclusion : Trinomial can not be factoredSolution:
[tex]3x^2 + 18x - 13[/tex].Answer:
[tex]\boxed{\tt \tt 3x^2+18x-13}[/tex]
Step-by-step explanation:
[tex]\tt -3x(7x-4)+6x-(13-24x^2)[/tex]
Apply the Distributive Property
[tex]\tt -3x\left(7x-4\right)+6x-13+24x^2[/tex]
Multiply, -3 by (7x-4):
[tex]\tt -21x^2+12x+6x-13+24x^2[/tex]
Combine like terms:

What is an equation of the line that passes through the point (-7, -6) and is parallel to the line x-y=7?
If you’re answer is correct, I WILL GIVE BRAINLIEST!!! Thank you!:)
Answer:
Step-by-step explanation:
For two lines to be parallel their slopes must be equal. For two lines to be perpendicular their slopes must be the negative reciprocal of each other.
Step 1 Find the slope of the equation.
Put it into the slope-intercept form. y = mx + b.
For x-y = 7, move the x to the left; therefore subtract the x from both sides. this leaves you -y = -x + 7
Then, divide both sides by -1 to get a positive y. -y/-1 = (-x + 7)/-1
This leaves y = x - 7 The slope(m) for this equation is m = 1
The other equation must also have a slope of 1 or m=1 for the lines to be parallel.
Use the point given to you (-7, -6) and substitute for (x, y)
The slope-intercept form y = mx + b can once again be used.
x = -7, y =-6, and slope or m = 1
Therefore, y = mx + b substituted will be -6 = (1)(-7) + b; now, solve for b which is the y intercept
-6 = -7 + b add 7 to both sides -6 +7 = -7 + b +7 ; therefore, b = 1
Now you know the slope(m) which is equal to 1 and the y-intercept(b) which is equal to 1.
Finally, substitute the m and b in the slope-intercept form
y = (1)x + 1 or y = x +1
- A six-foot diameter circular table
top has an area of about how many
square feet? (Use 3.14 for a.)
.
Answer:
28.26
Step-by-step explanation:
area of a circle is (pi)(r)^2
radius is half of the diameter
6/2=3
3 feet is the radius
a= 3.14 (3)^2
=3.14 x 9
= 28.26 feet

if f(x) = 2x^3 + Ax^2 +4x -5 and f(2)=5, then what is the value of A?
Answer:
[tex]\dfrac{-7}{2}[/tex]
Step-by-step explanation:
Here we are given a polynomial ,
[tex]\implies f(x) = 2x^3 + Ax^2 + 4x - 5 [/tex]
And the value of ,
[tex]\implies f(2) = 5 \dots (i) [/tex]
And we need to find out the value of A . Firstly substitute x = 2 in f(x) , we have ,
[tex]\implies f(2) = 2(2)^3+ A(2)^2 + 4(2) -5 [/tex]
Simplify the exponents ,
[tex]\implies f(2) = 2(8) + A(4) + 8 - 5 [/tex]
Simplify by multiplying ,
[tex]\implies f(2) = 16 + 4A + 3 [/tex]
Add the constants ,
[tex]\implies f(2) = 19 + 4A [/tex]
Now from equation (i) , we have ,
[tex]\implies 19 + 4A = 5 [/tex]
Subtracting 19 both sides,
[tex]\implies 4A = 5-19 [/tex]
Simplify,
[tex]\implies 4A = -14[/tex]
Divide both sides by 4 ,
[tex]\implies A =\dfrac{-14}{4}=\boxed{ \dfrac{-7}{2}}[/tex]
Hence the value of A is -7/2.
As you were organizing your closet you counted 20 shirts and 12 pairs of pants what was the pants to shirt ratio?
Answer is the ratio 3:5
Explanation:
To write the pants to shirt ratio, we write the numbers 12 and 20 in that order (since they correspond to the counts of each clothing item). Separate them with a colon to get 12:20
The last step is to divide both parts by the GCF 4
12/4 = 3
20/4 = 5
The ratio 12:20 fully reduces to 3:5
For every 3 pairs of pants, you have 5 shirts.

Which expression is equivalent to
n^3⋅n^−8?
Answer:
1/n^5
Step-by-step explanation:
Apply exponent rule : a^b * a^c = a^b+c
= n^3-8
Subtract the numbers.
= n^-5
Apply exponent rule : a^-b = 1/a^b
n^-5 = 1/n^5

A rectangular prism has a volume of 60 cubic centimeters. If you triple the length of this rectangular prism, what will its new volume be? A rectangular prism has a volume of 60 cubic centimeters. If you triple the length of this rectangular prism, what will its new volume be?
216,000 cm3
63 cm3
20 cm3
180 cm3
Step-by-step explanation:
the volume of such an object is created by multiplying the 3 side length dimensions :
length × width × height.
if you triple one of them, then you bring that factor 3 one time into the volume multiplication, and the volume also triples .
in our case that is 60×3 = 180.
FYI
if you would triple fire example all 3 dimension lengths, you would bring that factor 3 into the volume multiplication 3 times (once for every dimension).
and so the volume would increase by the factor
3×3×3 = 27.
three numbers are in an arithmetic progression. Their sum is 3 and the sum of their squares is 11. what are the three numbers
The three numbers are 12, 18 and 24
Arithmetic progression
Let the 3 number in arithmetic progression be:
a-d, d, a+d ...
If their sum is 3, then;
a-d+d+a+d = 3
2a + d = 3 ........... 1
If the sum of their squares is 11, then;
(a-d)² + d² + (a+d)² = 11
a²-2ad+d²+d²+a²+2ad+d² 11
2a²+3d² = 11 ....... 2
Solving the equations simultaneously, d = 6 and a = 12
First-term = 12
second term = 18
Thirs term = 24
Hence the three numbers are 12, 18 and 24
Hope this helps you!!!!!! :D
Answer:
-3, 1, -1 or -1, 1, 3
Step-by-step explanation:
We can create the equation of x + x+d + x+2d = 3 or use the sum formula to end up with x = 1-d.
We can then calculate d by using 11 and creating an equation like this.
x^2 + (x+d)^2 + (x+2d)^2 = 11 -> (1-d)^2 + (1)^2 + (1+d)^2 =11 which ends up with d equaling -2 or 2
If we plug d into the sum formula we get
(2x + 2 * 2)/2 *3 =3
and
(2x + 2 * -2)/2 *3 =3
This leaves us with starting terms -1 and 3. We can then finish the arithmetic sequence for each case by just using d.

what is the surface area of this triangular prism
[tex]\huge\boxed{\fcolorbox{black}{green}{Answer}}[/tex]
The surface area of this prism consists of:
Sprism = Sprism + Ssides
the bases of triangles the area of each one is
Atriangle = 1/2bh
Aonebases = 1/2bh
Abothbases = 2×1/2×bh = bh
Arectangle = l×w where l is the length and w is the width
Aside = ls
If the triangular base has unequal sides then you calculate the perimeter( P) of the triangle and multiply it by the height of the prism to get the area of the sides (lateral surface area)
If the base is an equilateral triangle then all three sides have equal areas and the lateral surface area becomes = 3ls
Sprism = bh+pl

Answer:m<c=120
Step-by-step explanation:
You set the two expressions equal to each other solve for x and then plug in x to one expression to get the angle.
After that add the two angles together and subtract them from 360 divide by two and you’ll get the other two angles.
This usually only applies to parallelograms.
I hope this helps it’s been awhile since I’ve done this so if it sounds like gibberish I worked out the problem as a better explanation.

Anyone mind helping me!?
Answer:
see explanation
Step-by-step explanation:
3x² + 5x + 2 = 0
(a)
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 2 = 6 and sum = 5
The factors are + 3 and + 2
Use these factors to split the x- term
3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )
3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(3x + 2) = 0
(b)
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]
A coffee table is on sale for 20% off the original price of $115. If there is 7.5% sales tax, what is the final price of the coffee table? HURRY ILL GIVE BRAINLIEST IF CORRECT
Answer:
98.9
Step-by-step explanation:
115 - 20% = 92
92 + 7.5% = 98.9
Answer:
the original price is 115 after we subtract 20% we are left with 92 so now
the price of the coffee table is 92 but with 7.5% as tax, the final price is $98.90 since 7.5% of 92 is 6.90
